To save some time if they have this issue in the future please check to see if your nginx configuration is conflicting with apache's.
You can find this under Domain>>Apache & nginx Settings>>nginx settings and check "Proxy Mode" and "Smart Statif files processing" in your Plesk Panel. Save and try again and it should work
Again this is just a "How To" rather than a question. Good Luck!
